(01'. 215-4) ...This invention relates to metal siphonheads for mineral watenbottles of. thekind provided with a lever foroperating-theyalve, and has for i s object to. improve the method ofmanufacture and likewise the construction of such siphon heads so as toconsiderably reduce.,the cost of production whilegin creasing theefliciency and str lgth and durability thereof ,Siphon heads ofthekindireferred; to are usually cast in tinorother metals and alloyswith and without porcelain, glass and other linings, and. comprise abody portion furnished with a discharge spout and an internal waterwaythat is normally closedby the valve, the upper part of-zthesiphon headserving to house, the valve gear and operating lever, and being providedwith a, removable cap, while the skirt or lower portion of. thebody issecured to a siphon. bottle or the like by means of asplit ring mountedupon the exterior-of the. bottle neck...

According to the present inventionthe body, discharge spout :andvinternal partitions .of a metal-siphon head. ofthekindreferred to areformed from cupro-nickel or other suitable sheet metal blanks or tubes;sothatsuch elementscan be ,readily and accurately as'seinbledmnd securedtogether to form the siphon head, the removable cap of which latter isadapted to form a guide for the head of the valve spindle soas to secureaccurate alignment of the valve with its seating, while the split neckring by which the siphon head is secured to the siphon bottle or vasemay be formed from a blank or blanks of cupro-nickel or other suitablemetal, and is furnished with an internal soft metal or other suitablepacking so as to prevent injury to the neck of the bottle or vase onwhich it is fitted.

The invention is further described with reference to the accompanyingdrawing, wherein similar references indicate like parts.

Fig. 1 is a vertical section illustrating one embodiment of theinvention in a short lever mineral water siphon head; Fig. 2 is afragmental vertical section on the line II-II Fig. 1, while Figs. 3-8inclusive are detail views presently referred to further illustratingthe construction of siphon head illustrated at Fig. 1.

Referring to the drawing, the siphon head comprises a body or shell Isub-divided internally by perforated horizontal partitions 6 and I andfurnished with a spout l2, each of which elements is drawn down ordie-pressed in one piece to the required shape and dimensions from anappropriate tube or blank of cupro-nickel or other suitable metal sothat the same can be accurately assembled and; soldered "or otherwise;securedlito- .gether as indicated at Fig. 1 to form the siphon head. aya. 1 The body shell I; is aperturedgonpne. side at 2 to receive,.one-.=end of; the spout-:12- andyais 5 slotted on itsopposite =side.-at r3tto=raccommodate the-.Yalve .lever, while. its.upperxportiomterminates in anexpanded internallythreaded open end Iafor the receptionofthe screwpap i5. .1; a 1: 1 a The partition 6- :is.:formed by the centrallyper- 10 forated closed end of acup-or; sleeve1, the-open end of ,which is expanded; and slotted on opposite sidesatla 'lb as shomi-at Fig. 5,-suchsleeve being vinserted in;.the upperpart .ofthebody 1 shell so,, that the. slotsltherein register with vtheslot 3 in the shell, while the lower. end of the sleeve slightlyoverlaps the spout aperture land forms an abutment for the inner end of,the

I; 2.. e. The partition Hl-is stepped to form a central recess I00,and-a peripheralflange lob, such-partition being soldered or otherwisesecured in the lower part. lof the; body ishell so as to abut the.innerlend. of;;=;the;spout;|2::aszindicated at Fig. 1.

The partitions; 6:,and ID. are. arranged incthe body, shell .withtheir,,,centralg ,perforations:in alignment with each other, so that thespindle 8 of the valve 9 can work therethrough, the perforation in theupper partition 6 forming a guide for the valve spindle while theperforation H in the lower partition I0 is of sufiicient diameter toform the waterway past the valve stem.

The upper partition 6 carries the perforated packing washers l3 for thevalve stem together .with the valve spring M which is mounted betweenthe packing washers and a head or plunger l5 secured to the upper end ofthe valve spindle 8, the lower end of which carries the valve 9 whichnormally seats against a perforated valve seating piece 9a housed in thecentral recess Illa 4 of the lower partition I.

The head or plunger [5 at the upper end of the valve spindle 8 is ofcircular cross section and is formed with a central vertical slot l5a inwhich is secured a cross pin l8 so as to form a bearing for the valveoperating lever l9 which is shaped so as to pass through the slot 3 inthe body shell I and the slots 1a'|b in the sleeve 1, and is recessed asindicated at l9a for engagement with the cross pin ill in the head l5 ofthe valve spindle.

The cap 5 is formed with a central recess 5a and is adapted to screwinto the open upper end Id of the siphon head body a sufiicient distancefor its central recess to engage the head I 5 0t the valve stem 8 andthus form a guide for the latter, while the inner end 5c\ of the capserves as a fulcrum for the inner end I9b of the valveing the siphonbottle or the like on which the head is mounted and thus preventsinadvertent operation of the valve.

The skirt or lower end lb of the body shell is internally screw threadedfor engagement with an externally threaded split neck ring 2| by meansof which it is mounted in known manner upon the neck of the siphonbottle, vase or the like indicated at A Fig. 1.

In accordance with the present invention the neck ring 2| is made ofsufficient internal diameter to accommodate a soft metal, fibre or othersuitable packing 22 and is formed with an internal flange 23 whichserves to support the packing, while such improved neck ring may be castin the ordinary manner or be die-pressed from a suitable metal blank orblanks. In the construction illustrated, the neck ring is die pressedfrom a blank or blanks of cupro-nickel or other suitable sheet metal soas to support a divided soft metal packing ring 22 which projectsslightly above the upper edge of the neck ring and engages the externalclip or collar w so shielding the same from contact with the threadedneck ring.

A suitable neck washer b is interposed as usual between the mouth of thesiphon bottle A and the adjacent face of the lower partition IU of thesiphon head so as to take the thrust of the latter as it is screwed onto the neck ring 2|. In the construction illustrated the neck washer bforms an elastic support for the externally flanged siphon tube carrier0 which is clamped between the neck washer and the elastic valve seatingwhen the siphon head is secured in position on the neck ring.

What I claim is:-

1. A mineral water siphon head comprising an apertured body shellinternally sub-divided by two centrally perforated partitions andfurnished with a spout and a removable cap adapted to co-operate with ahead on the valve spindle and form a guide therefor.

2. A mineral water siphon head according to claim 1 having an internallyflanged split neck ring furnished with an internal packing supported bythe internal flange of said neck ring for securing the siphon head tothe neck of the siphon bottle or like container.

3. A siphon head comprising a body, a pair of transverse partitions inthe body and spaced apart, a spout extending from the body and havingits inlet end arranged in the space between said partitions, a capforming a closure for the outer end of the body, a valve having aspindle passing through the partitions, a head on the outer end of thevalve spindle and a valve operating lever fulcrumed in said head and atits inner end abutting against the inner side of said cap.

4. A siphon head as claimed in claim 3, in which the head on the valvespindle has a transverse slot to receive the lever and is also providedwith a fulcrum pin extending across the slot and the lever is providedwith an inwardly opening slot to receive the fulcrum pin.

5. The method of constructing metal siphon heads consisting inseparately forming a body shell provided with a spout aperture in itswall,

internal partitions for said body shell and a discharge spout, and thenassembling and securing these elements together by first inserting onepartition in said body shell so that it slightly overlaps the spoutaperture and forms an abutment for the inner end of the spout; thenattaching the, spout to the body shell, and then inserting a secondpartition in said body shell and securing it in place when it has beenbrought into engagement with said spout forming an abutment for saidsecond partition.
